Pistils Nursery 3811 N. Mississippi Ave Portland, Oregon
I have not been here personally, but they came highly recommended by our next door neighbor who has the most beautiful garden imaginable!
She spoke highly of their knowledgeable staff and having spoken to several of them I concur.
We have two areas, one to the right and the other to the left, off our patio where we hope to plant flowers on one and a small vegetable patch on the other come spring.
I had originally posted this in another thread but hopefully it'll be useful here too!
